RELATED APPLICATION(S)

This application is a non-provisional application of co-pending and commonly assigned U.S. Provisional Patent Application No. 61/862,637, filed on Aug. 6, 2013, from which benefits under 35 USC §119(e) are hereby claimed and the contents of which are hereby incorporated by reference herein.

TECHNICAL FIELD

The disclosure relates to wireless network data collection on an electronic device.

BACKGROUND

Electronic devices, such as smartphones, tablets, and other electronics, are often used with applications (“apps”) that provide automated features to the user based on a location of the electronic device, such as a point of interest. For example, a user located in their home may wish to be notified by a loud ringtone when a call is received, while automatically silencing the ringtone when the user is located at their place of work. The smartphone may determine its location via the Global Positioning System (GPS) and provide the automated features based on the location. However, the smartphone typically increases its power consumption in order to use the GPS feature. This increased power consumption reduces the smartphone's battery life more quickly. The smartphone may also determine its location by scanning for wireless access point IDs for WiFi networks and performing a lookup on each wireless access point ID for known associated locations. However, frequent scanning and performing the lookup also typically increase the smartphone's power consumption and reduces the battery life more quickly.

DETAILED DESCRIPTION

While several methods or technologies (e.g., GPS, WiFi, cell tower ID) may be available to a smartphone (or other electronic device) for determination of its location, it is desirable to efficiently use these methods to conserve the smartphone's battery life. A GPS component that determines the smartphone's location may provide high accuracy, but with significant power consumption. A cell tower ID may be used to determine the location with a low level of accuracy, but minimal power consumption as compared to typical operation of the smartphone. A WiFi-enabled smartphone may scan for wireless access point IDs for WiFi networks, which may then be used for determining the smartphone's location with moderate accuracy. However, each scan consumes additional power. The smartphone detects and collects wireless access point IDs during the scan, but must also perform a lookup (e.g., through Google Location Services) to determine a location that corresponds to each wireless access point ID. Once the location of the wireless access point associated with the wireless access point ID is determined, the smartphone may provide the automated features based on that location upon detection of the wireless access point ID.

The present disclosure is generally directed to a method and system for collecting wireless network data. In particular, the disclosure is directed to determining geographic information for wireless access points and associating selected wireless access points with points of interest.

The present disclosure describes a method. A first set of unique wireless access point IDs is collected. A second set of unique wireless access point IDs is collected. The first set and the second set are compared to determine intersecting wireless access point IDs and non-intersecting wireless access point IDs of the second set. If the number of intersecting wireless access point IDs meets an intersection threshold for the first set, the non-intersecting wireless access point IDs of the second set are added to the first set. A confidence level is updated for the unique wireless access point IDs of the first set that correspond to the intersecting wireless access point IDs. Geographic information is determined for the unique wireless access point IDs of the first set that meet a confidence threshold.

The present disclosure further describes a method. Data is collected regarding unique wireless access point IDs detected by the electronic device, the frequency with which the unique wireless access point IDs are detected, and the time of day at which the unique wireless access point IDs are detected. The collected data is compared with a set of criteria for a point of interest. A set of unique wireless access point IDs is associated with the point of interest based on the comparing step.

The present disclosure further describes an electronic device for a wireless network. The electronic device includes a non-transitory memory and a processor configured to retrieve instructions from the memory. The electronic device is configured to collect a first set of unique wireless access point IDs. The electronic device is configured to collect a second set of unique wireless access point IDs. The electronic device is configured to compare the first set and the second set to determine intersecting wireless access point IDs and non-intersecting wireless access point IDs of the second set. The electronic device is configured to add the non-intersecting wireless access point IDs of the second set to the first set if the number of intersecting wireless access point IDs meets an intersection threshold for the first set. The electronic device is configured to update a confidence level for the unique wireless access point IDs of the first set that correspond to the intersecting wireless access point IDs. The electronic device is configured to determine geographic information for the unique wireless access point IDs of the first set that meet a confidence threshold.

Turning to FIG. 1, an electronic device 100 is shown, according to an embodiment. The electronic device 100 includes a processor 102, a memory 104, a WiFi component 106, and a location component 108. The electronic device 100 may further include one or more user applications 109 (e.g., an “app”). The WiFi component 106 provides a wireless network capability to the electronic device 100, using one or more wireless access standards. In the embodiments described herein, the IEEE 802.11 standard is used. However, other wireless network standards may be used and will be apparent to those skilled in the art. The WiFi component 106 is configured to detect wireless access points (“WAPs”). The WiFi component 106 may be further configured to establish a communication channel with wireless access points for data communication.

The WiFi component 106 detects one or more wireless access points 110, for example, wireless access points 112 and 114. The wireless access points 110 may be identified by respective unique wireless access point IDs. Examples of the unique wireless access point ID may include a basic service set ID (BSSID), a media access control (MAC) address, an interne protocol (IP) address, another unique identifier, or any combination thereof. In one embodiment, the unique wireless access point ID is the BSSID because they are unique. Some wireless networks may cover a large geographical area through the use of many wireless access points. In this case, a single SSID or network name (e.g., “Free Public WiFi”) may be available in multiple remote locations, making this network name a less accurate identifier for locations.

The wireless access points 112 and 114 are shown in FIG. 1 as wireless access points for wireless networks 122 and 124, respectively. In alternative embodiments, a wireless network may include multiple wireless access points, as will be apparent to those skilled in the art. The wireless networks 122 and 124 may be identified by a network identifier, such as a network name, a service set ID (SSID), an extended service set ID (ESSID), or any combination thereof.

The electronic device 100 is configured to initiate a scan for wireless access point data by the WiFi component 106. The wireless access point data may include unique wireless access point IDs, received signal strength indicators (RSSIs), network identifiers, or other information. The electronic device 100 in one example initiates the scan by an instruction from an operating system (not shown) of the electronic device 100. In another example, the electronic device 100 initiates the scan by an instruction from the user application 109 (e.g., a “Google Maps” app) executed by the electronic device 100. The electronic device 100 may execute a plurality of user applications 109 that initiate their own scan for unique wireless access point IDs. In yet another example, the location component 108 may initiate the scan, as described herein.

As a result of the scan, the WiFi component 106 may detect a set of unique wireless access point IDs. The WiFi component 106 may store the set of unique wireless access point IDs detected during a scan in the WiFi component 106, the memory 104, or a combination thereof. The WiFi component 106 may receive the detected unique wireless access point IDs in a message from the wireless access points 110, such as a beacon frame or other broadcast message. The WiFi component 106 may also actively message a preselected wireless access point, as in the case of a wireless access point that is configured to suppress the beaconing of its SSID. For example, a user may not wish to broadcast the SSID of their wireless network to reduce connection attempts by unauthorized users. In this case, the user may preselect the wireless access point and store its unique wireless access point ID so that during a scan, the WiFi component 106 messages the preselected wireless access point to determine its availability. The WiFi component 106 may detect the unique wireless access point ID based on a response to the message, as will be apparent to those skilled in the art. Accordingly, the electronic device 100 does not need to establish a communication channel with the wireless access point in order for the unique wireless access point ID to be detected.

The location component 108 is configured to collect and process wireless access point data, as described herein. The location component 108 may receive wireless access point data from the WiFi component 106 directly, from the memory 104, from the user application 109, or any combination thereof. Because the unique wireless access point IDs were detected during a single scan, it may be presumed that the corresponding wireless access points are near a same location. The location component 108 in one example stores records with unique wireless access point IDs that have been detected. The record may include the set of unique wireless access point ID and corresponding data, such as received signal strength indicators (RSSIs), detection times, detection durations, detection counts, confidence levels, location information, or other information. The location component 108 may be configured to determine a location for a point of interest (“POI”) based on the records. The location component 108 may be further configured to determine when the electronic device 100 has arrived at or departed the point of interest. Examples of points of interest include a user's workplace, home, school, or other location. The location component 108 may create a point of interest based on collected data or preselected parameters (e.g., a time of day, day of the week, etc.). The point of interest may be used by the operating system of the electronic device 100 or the user applications 109, for example, via a “Smart Apps” feature.

The location component 108 is configured to obtain location information for a wireless access point. The location component 108 may use Google Location Services data or other external databases that correlate unique wireless access point IDs (e.g., BSSIDs) to geographical coordinates, a time zone, street address, zip code, other location information, or a combination thereof. The location component 108 may also determine a geographic proximity between at least two wireless access points based on a received signal strength indication for the wireless access points. For simplicity, the discussion herein may refer to location information for a unique wireless access point ID, which may be understood to mean the location information of the wireless access point that corresponds to the unique wireless access point ID.

FIG. 2 is a flowchart of a method 200 for collection of wireless access point data that may be performed by the location component 108 of the electronic device 100, according to an embodiment. The location component 108 collects (202) wireless access point data. In one embodiment, the location component 108 waits for a scan by the WiFi component 106 to be initiated by the operating system, the user application 109, or other initiator. In this case, the location component 108 reduces a number of scans performed by the WiFi component 106, thus reducing power consumption. The location component 108 may also initiate the scan after an expiration of a timer. For example, the location component 108 may initiate the scan if a time since a previous scan meets a collection threshold. The collection threshold may be a fixed time period, such as fifteen minutes, or the location component 108 may dynamically adjust the collection threshold.

As a result of the scan, the location component 108 collects a set of unique wireless access point IDs (“collected set”). The location component 108 determines (204) whether a previous record of unique wireless access point IDs is available. If no previous record is available (NO at 204), the location component 108 creates (206) a new record for the set of unique wireless access point IDs.

If previous records are available (YES at 204), the location component 108 determines (208) whether the collected set intersects with a set of unique wireless access point IDs from a previous record (“record set”). For example, the location component 108 compares the collected set and the record set to determine intersecting wireless access point IDs and non-intersecting wireless access point IDs of the collected set. As one example, the collected set may include unique wireless access point IDs A, B, C, D, and E. The record set may include unique wireless access point IDs A, B, C, D, and X. In this example, unique wireless access point IDs A, B, C, and D are intersecting wireless access point IDs and unique wireless access point ID E is a non-intersecting wireless access point ID.

If the number of intersecting wireless access point IDs meets an intersection threshold for the record set (YES at 208), the location component 108 updates (210) the record set. For example, the location component 108 adds the non-intersecting wireless access point IDs (“E”) to the record set. If the number of intersecting wireless access point IDs does not meet the intersection threshold (NO at 208), the location component 108 creates (206) a new record for the collected set. In an embodiment, the intersection threshold is a preselected percentage of a number of unique wireless access point IDs of the record set. With a preselected percentage of 80% and the previously described access point IDs as one example, the intersection threshold is 80% of five (for A, B, C, D, and X), which is four. Accordingly, the collected set intersects with the record set because four entries (A, B, C, and D) of the collected set match the record set. The use of a preselected percentage may reduce sensitivity to unique wireless access point IDs that are intermittently detected (e.g., due to low signal strength, being powered off, being moved, or part of a mobile access point within an automobile). In another embodiment, the intersection threshold is a fixed number (e.g., 1, 4, 5, etc.). The location component 108 in another embodiment uses a dynamic intersection threshold, for example, based on a confidence level of the record. In yet another embodiment, the location component 108 may use multiple intersection thresholds for determining intersection.

Upon creation of a new record, the location component 108 initializes a confidence level for the record. The confidence level may include a number of times that the unique wireless access point IDs within the record have been detected over a period of time (e.g., a detection count), a duration of time in which they have been detected (e.g., a detection time), a point value, or any combination thereof. The record may include an overall confidence level for the entire record, separate confidence levels for each unique wireless access point ID within the record, or both.

When updating (210) the record, the location component 108 updates the confidence levels based on the collected set. For example, where the confidence level is a detection count, the record may include a confidence level of 4, 5, 5, 4, and 3 for the unique wireless access point IDs A, B, C, D, and X, respectively. After the update, the record may include a confidence level of 5, 6, 6, 5, 1, and 3 for the unique wireless access point IDs A, B, C, D, E, and X, respectively. In another embodiment, the confidence level may be an overall confidence level of 4 for the record set, such that after the update, the confidence level for the record set is 5.

In yet another embodiment, the confidence level may be a point value. The location component 108 may increase the point value based on a detection count or detection duration. The location component 108 may further increase the point value based on a time of day for the detection. For example, the point value may be increased by two points for each detection count during a predetermined “high value” time period and increased by one point for each detection count outside of the high value time period. The predetermined “high value” time period may be a time period likely to be associated with a point of interest, such as a user's workplace (e.g., 11:00 am to 2:00 pm) or home (e.g., 2:00 am to 4:00 am).

After creation of the new record (206) or updating (210), the location component 108 determines (212) whether a record has a confidence level that meets a confidence threshold and also whether the record includes location information. The confidence threshold may be a detection count, detection time, or a combination thereof. If no record has met the confidence threshold (NO at 212), the location component 108 resumes collecting data (202). If a record has met the confidence threshold but already has location information (NO at 212), the location component 108 resumes collecting data (202). If a record meets the confidence threshold and does not have location information (YES at 212), the location component 108 obtains (214) location information for the record, as described above.

Determining (212) whether the record meets the confidence threshold or obtaining the location information may be performed at later times. The location component 108 in one example waits to perform these steps to reduce a drain on a battery of the electronic device 100. For example, the location component 108 may wait for the electronic device 100 to be plugged into a source of electrical power or coupled with a high speed network (e.g., to reduce a transfer time for obtaining the location information).

FIG. 3 is a flowchart of a method for determination of points of interest that may be performed by the location component 108 of the electronic device 100, according to an embodiment. The location component 108 collects (302) wireless access point data, for example, as described above with reference to FIG. 2. The location component 108 compares (304) the collected data (e.g., the records) with a set of criteria for a point of interest. The set of criteria may include at least one of a time range, detection count, a geographic distance, or others, as will be apparent to those skilled in the art. The location component 108 associates (306) a selected set of unique wireless access point IDs with the point of interest based on the comparison (304). For example, the location component 108 may select the set of unique wireless access point IDs that are within a geographic distance of each other. The geographic distance may be a fixed value, or dynamically selected (e.g., based on the number of records, or other factors). As one example, the location component 108 may select a set of unique wireless access point IDs that are within 50 meters of each other for a first point of interest. As another example, the location component 108 may select the set such that the unique wireless access point IDs are within 100 meters and detected during a time period of 10:00 am and 2:00 pm during weekdays for a second “work” point of interest. The location component 108 may identify one or more of the unique wireless access point IDs as being along an outer perimeter of the point of interest (e.g., to simplify calculations for determining entry into the point of interest).

After associating the unique wireless access point IDs with the point of interest, the location component 108 calculates (308) a centroid for the point of interest. In one example, the location component 108 calculates the centroid based on the geographic locations of the set of unique wireless access point IDs associated with the point of interest. In a further example, the location component 108 may weight the geographic locations based on their respective detection counts and/or times of day. The location component 108 may also weight the geographic locations based on their respective received signal strength indications. Additional criteria for calculating the centroid will be apparent to those skilled in the art.

FIG. 4 is a flowchart of a method for updating point of interest data that may be performed by the electronic device of FIG. 1, according to an embodiment. After the location component 108 has associated the unique wireless access point IDs with a point of interest, the location component 108 collects (402) wireless access point data (e.g. newly detected data from a current scan). The location component 108 compares (404) the collected data from a current scan of unique wireless access point IDs with the set of unique wireless access point IDs associated with the point of interest to determine current intersecting wireless access point IDs. The location component 108 determines (406) whether the electronic device 100 has arrived at the point of interest if a number of current intersecting wireless access point IDs meets an arrival threshold. The arrival threshold may be based on a preselected percentage of a number of associated unique wireless access point IDs for the point of interest (e.g., 20%, 50%, etc.), a fixed number (e.g., 1, 2, 5, etc.), a dynamic threshold based on a confidence level of the record, a received signal strength indicator (RSSI), or a combination thereof. If the location component 108 determines that the arrival threshold is not met (NO at 406), the location component 108 continues to collect (402) data.

If the arrival threshold is met (YES at 406), the location component 108 may set (407) an arrival status (e.g., for the user application 109 or the operating system of the electronic device 100) that indicates that the electronic device 100 has arrived at the point of interest. The location component 108 collects (408) wireless access point data after arrival at the point of interest (e.g., with one or more subsequent scans). The location component 108 compares the subsequent scan of unique wireless access point IDs with the set of unique wireless access point IDs associated with the point of interest to determine (410) whether a number of subsequent intersecting wireless access point IDs meets a departure threshold. The departure threshold may be based on a preselected percentage of a number of associated unique wireless access point IDs for the point of interest (e.g., 20%, 50%, etc.), a fixed number (e.g., 1, 2, 5, etc.), a dynamic threshold based on a confidence level of the record, a received signal strength indicator (RSSI), a detection time, a detection duration, a distance from the centroid, a distance from a unique wireless access point ID of the point of interest, or a combination thereof. One example of a departure threshold is having none of the unique wireless access point IDs detected within three minutes. Another example of the departure threshold is having one unique wireless access point ID detected in the subsequent scan. Yet another example of the departure threshold is having none of the unique wireless access point IDs detected within two minutes and a location of a selected unique wireless access point ID of the subsequent scan being outside a proximity threshold (e.g., 75 meters). The unique wireless access point ID may be selected based on the received signal strength indicator (e.g., a strongest RSSI).

If the departure threshold is not met (NO at 410), the location component 108 continues collecting (408) wireless access point data. If the departure threshold is met (YES at 410), the location component 108 updates (411) the arrival status to indicate that the electronic device 100 has tentatively departed from the point of interest. The location component 108 determines (412) whether a departure update threshold is met. The departure update threshold may be based on a preselected percentage of a number of associated unique wireless access point IDs for the point of interest (e.g., 20%, 50%, etc.), a fixed number (e.g., 1, 2, 5, etc.), a dynamic threshold based on a confidence level of the record, a received signal strength indicator (RSSI), a detection time, a detection duration, a distance from the centroid, a distance from a unique wireless access point ID of the point of interest, or a combination thereof. The departure update threshold indicates that the electronic device 100 has stayed near the point of interest. For example, where the departure threshold is two minutes and 75 meters, the departure update threshold may be five minutes and 75 meters. The location component 108 may also evaluate a speed of the electronic device 100 for the departure update threshold, for example, whether the user of the electronic device 100 is likely to be walking (e.g., more likely to be in the same location) or driving (e.g., less likely to be in the same location).

If the distance between the centroid and the selected wireless access point ID is within the departure update threshold (YES at 412), the location component 108 adds (414) the selected wireless access point ID of the subsequent scan to the set of unique wireless access point IDs associated with the point of interest and updates the arrival status to indicate arrival at the point of interest. After addition of a wireless access point ID, the location component 108 may re-calculate (416) the centroid for the point of interest using the location information associated with the selected wireless access point ID. If the departure update threshold is not met (NO at 412), the location component 108 updates (413) the arrival status to indicate that the electronic device 100 has departed from the point of interest and returns to collect (402) wireless access point data.

The methods of FIGS. 3 and 4 may be applied to multiple points of interest for the electrical device 100. In one example, the location component 108 compares the unique wireless access point IDs for multiple points of interest to determine whether they intersect. The location component 108 may ignore or omit a point of interest if it intersects another point of interest.
